How to capture a bird: ornithological photographs by Todd R Forsgren

Before a bird can be weighed, measured and given the tiny aluminium anklet that will allow its movements to be monitored in the wild, it must first be captured in a so-called 'mist net' with mesh as fine as a spider's web.
Photographer Todd R Forsgren, whose father inspired his lifelong love of birds, has spent years making portraits of the moment of their capture. His images are collected in a new book, Ornithological Photographs. Details: daylightbooks.org
